To all whom t may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residing at @ak Park, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Sliocking-li/iachines, of which the following is a full, clear, and exact specification.

My invention relates to shocking machines.

In shocking machines of the swinging sheaf delivery member type, wherein a sheaf delivery member with tines thereon is used to convey the sheaves from a point adjacent the binder deck to the sheaf receiving cradle of the shocker, it has been found that in certain cases in slippery grain, there is a tendency for the sheaf to shift longitudinally with respect to the sheaf de-' livery member, resulting in the sheaves being positioned irregularly with respect to the end tines of the cradle so that, when the cradle is operated, the butts of the sheaves not being disposed in the same plane, a shock of inferior standing quality is formed. lt has further been found that in certain similar grain conditions there has been a tendency for the sheaf to drop downward from the sheaf delivery member after the latter hasv passed over its center and before the sheaf is properly positioned over the cradle as the sheaf delivery member moves downward, with the result that the sheaves have been set irregularly in the cradle and the standing qualities of the shock have been deleteriously affected.

My invention has for its object to hold the sheaf securely in position upon the sheaf delivery member as the latter moves from sheaf receiving to sheaf delivery position, in such a manner that the sheaf will be held against longitudinal shifting with respect to the fork in the manner noted, and at the same time will be so held as to be unable to leave the fork prematurely in the objectionable manner mentioned. I attain these objects by the provision of improved holding means for retaining` the sheaf on the sheaf delivery member, comprising a tine having means thereon which, when the fork is driven into the sheaf, is likewise forced into the sheaf and, on account of its shape, acts to prevent both longitudinal movement of the sheaf with re- Specicatcn of Letters Patent.

spect to the sheaf delivery member, and premature separation of the sheaf therefrom.

In the accompanying` drawings l have shown one form which my invention may assume in practice.

Figure l shows a top plan view of a sheaf delivery member equipped with my improvement Fig. 2 shows a side elevation of the sheaf delivery member in position beneath a sheaf; and

Fig. 3 is a sectional view of the sheaf delivery member taken on line 3--8 of Fig. 2, the sheaf being shown in position on the latter and in section.

ln the construction shown l have illustrated a sheaf delivery member l of the well-known Raney type, carried on a rotatable shaft 2 and attached thereto by suitable means 3. As in the usual Haney fork, a plurality of pairs of spaced parallel upstanding tines 4t are provided upon the free end of the same, each pair of tines preferably being formed from the same piece of stock and the latter being disposed transversely of the fork body and attached thereto by any suitable means. Fitting over the free endv of the fork l is also a tined member 5 having` three upstanding tines 6 thereon disposed in a substantially triangular form, while intermediate the two sets of tines 4L is a supplemental tine 7 secured directly upon the body of the fork, and on the shocker side of the inner tine 4 a second supplemental tine 8 is provided7 similarly secured to the fork; the end tines serving to penetrate the body of the. sheaf near the butt, while the tines? and 8 penetrate the same on opposite sides of the band.

In the form of my improved construction illustrated herein this last tine 8 is so formed as to coperate with the other tines in holding the sheaf in an improved manner. In the embodiment of my invention y shown herein this tine 8 is flattened between its ends, as shown in Fig. 3, in such a manner that it widens gradually toward a point of maximum width a little over half way between its ends and toward its free end, and from that point tapers toward a point at its upper or free end; this tine being so positioned transversely with respect to the straws in the sheaf that the enlarged portion thereon forms a projection or extension over which thc grain in a sheaf slides as the tine is moved into or out of the sheaf, yet which acts at the same time to form a substantial abutment preventing longitudinal movement of the bound sheaf and, due to its increased width, also acts to resist momentarilyfa free downward slipping movement of the sheaf as the fork swings over to its inverted position.

Since the operation of a Raney shocker is well known and forms no part of the present invention per se, it seems unnecessary to describe the parts thereof in detail, it being suiicient to say that the fork 1 is swung back and forth from the position shown in Fig. 2, wherein it lies under the binder deck of a harvester, to an inverted position, wherein it is over the shocker cradle, being turned by suitable mechanism (not shown) and moving with the shaft 2, which is journaled in suitable bearings, likewise not shown. Obviously, when the fork moves upward from the position shown in Fig. 2, the tines thereon will be forced into the sheaf, penetrating the latter and carrying the same backward in an arc to turn the sheaf while swinging about the shaft Z as an axis. In this movement it is to be noted that the tine 8 forces back the straws and embeds itself in the body of the sheaf at a point where the straws are tightly bound; i. e., near the band, and that, due to its width, it also tends to obstruct and prevent longitudinal movement of the sheaf with respect to the fork during the swinging movement, and toward the end of that movement, through its increased width, likewise acts to retain the sheaf upon the fork for the brief interval necessary to prevent the sheaf from sliding oli' downward prematurely as the fork swings through its quick downward stroke. Obviously, when the fork is driven backward, however; that is, from sheaf delivering to sheaf receiving position, the tine 8 will then be readily withdrawn from' the sheaf by the well-known quick return movement of tie fork and the pull of gravity on the sheaf.

While l have in this application shown one specific form which my invention may assume in practice, it is to be understood that I desire to cover in this application all of those modification thereof functioning to obtain the same results and consisting of modliications thereof.

JV hat I claim as my invention, and desire to secure by Letters Patent, is:

1. A shocking machine sheaf delivery member having thereon intermediate its ends an upwardly extending tine, and means on said tine for spreading the inner stalks of a sheaf on said delivery member, thereby resisting bodily movement of the sheaf with respect to the delivery member.

2. A shocking machine sheaf delivery member having thereon an upwardly extending tine provided with a projecting edge disposed transversely with respect to the shank of said delivery member.

3. A shocking machine sheaf delivery member having` thereon an upwardly extending tine provided with oppositely extending projecting edges disposed transversely with respect to the`I` shank ofV said delivery member.

fl. A shocking machine sheaf delivery member having an upstanding flattened tine tapered toward its ends and disposed substantially transversely with respect to the shank of said sheaf delivery member.

5. A shocking machine sheaf delivery member having an upstanding tine provided with laterally extending edges intermediate its ends resisting bodily movement of a sheaf along or away from said sheaf delivery member.

6. ln combination, a sheaf delivery fork, and an upstanding flattened tine carried thereon and disposed transversely with respect thereto having tapered laterally extending enlarged portions on its sides spreading the straw in a sheaf near the band thereof as the sheaf is positioned thereon and resisting movement of the sheaf relative to said fork.

7. In combination, a sheaf delivery fork having longitudinally spaced pairs of upstanding tines thereon, the tines in each pair being themselves transversely spaced, and a supplemental tine engageable with a sheaf on the opposite side of its band from one of said pairs of tines, said tine having means thereon resisting a vlongitudinal movement of the sheaf with respect to the delivery member.

8. ln combination, a sheaf delivery fork having longitudinally disposed spaced pairs of upstanding tines therein, the tines in each pair being themselves transversely spaced, and a supplemental'tine engageable with a sheaf on the opposite side o f its band from one of said pairs of tines, said tine having means thereon for resisting a bodily movement of the sheaf along or away from said sheaf delivery fork.

In testimony whereof I affix my signature,

Vin the presence of two witnesses.
